IMPROVEMENT IN TREADLE ATTACHMENTS FOR SEWING-MACHINES. v

Specification forming part of Letters Patent No. 150,517] dated May 5.187,4; application filed v March 4, 1874.

To all whom t may concern:

Be it known that I, WILLIAM HAsLUP,`of Sidney, in the county of Shelbyand State of Ohio, have invented certain new and useful Improvements inMechanical Movements; and

I do hereby declare that the following is a full,

. forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in which-Figure 1is a plan view of my treadle mechanism. Fig. 2 is a verticalsection of the same, and Fig. 3 is a detached view of a part thereof.

A represents the stand or frame of a sewing or other4 machine, to beoperated by a treadle mechanism. In the front part of the stand or frameA, near the bottom, is a shaft a, upon which is fastened a sleeve orcollar, B, by means of a set-screw, b. From this sleeve or collarextends a short arm, d, to which arm is secured a shaft, C, extending atright angles toward both sides, as shown. On the shaft O are pivotedtwotreadles, Dand D', at their heels. These treadles are at their frontends or toes connected by a strap or belt, f, which passes over apulley, 71., mounted in a vertical bar or frame, E, attached to the mainframe or stand A at its upper end. The vlower end of D to ascend andforce the pitman G upward,

giving the wheel H the other half of its revolution, and so onalternately;

This forms a perfect walkin g-treadlein which no pressure is necessaryto be exerted by the heels of the operator.

The sleeve or collar B' may readily be adjusted on the shaft a to themost convenient position for the operator.

I am well aware that much has been done in devising treadle mechanismfor sewingma chines, and that the'various parts which go to make up myinvention are not in themselves new.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

The combination of shaft C and treadles D D with arm d, shaft a, belt f,pulley h, pitman G, and wheel H, substantially as and for the purposeset forth.

In testimony that I claim the foregoing as my own, I aihx my signaturein presence of two witnesses.
